气球携带碘化银焰弹增雨雪效果分析

利用2003—2017年观测资料，分析了喀左县采用气球携带碘化银焰弹方法人工增雨雪的效果。结果表明：天气形势为蒙古气旋、短波槽、冷涡时，取得的人工增雨雪效果较好。气球焰弹增雪播撒的高度在2000—4000 m，增雨的播撒高度在3000—5000 m，以稳定层状云中的层云、雨层云、高层云最明显。在-10℃温度条件下，冰核生成率平均为6.3×10¹³个/g；喀左县每年降水量平均为505.87 mm，比全市各县平均448.33 mm增加57.54 mm，每年增雨折合水量为1.29×10⁸ m³。气球焰弹增雨每年增加量为31.31 mm，增加降水7.007×10⁷ m³；投入产出比为1∶97.1。气球携带碘化银焰弹增雨雪方法可为其他地区相关业务提供科学参考和技术支撑。

The effectiveness analysis of the artificial precipitation enhancement technique with the silver idoinde (AgI) flame bomb carried by a balloon

In this paper,the effectiveness of the artificial precipitation enhancement technique by means of silver iodide (AgI) flame bomb carried by balloon in Kazuo of Chaoyang was analyzed on the basis of the experimental data from 2003 to 2017.The results show that the best effect is achieved under the three synoptic situations including Mongolia cyclone,short-wave trough,and cold-vertex.The experiments show that the optimal seeding heights of the flame bomb in the process of snow and rain enhancements are respectively 2000-4000 m and 3000-5000 m,especially for the St,Ns and As in the stable layer-form clouds.Under the condition of the temperature of -10℃,the average generative rate of ice nucleus is 6.3×10¹³ per gram.The average annual precipitation in Kazuo county is 505.87 mm and is 57.54 mm more than the other counties of the Chaoyang.The average annual amount of the increased rainfall is 129 million m³.Whereas,the increasing amount of annual rainfall from the artificial precipitation enhancement using the balloon flame bomb is 31.31 mm which is converted into the water of 7.007×10⁷ m³.The ratio of the input to the output is 1:97.1.The above-mentioned precipitation enhancement method is able to provide the scientific reference and technical support for relevant businesses in other areas.
